I did four swarm captures this season and all were successful.
I placed them in five frame nucs. I sprayed some honey laced sugar water on everything in the box including the bees before and after placing said swarm.
The swarms were, two from tree branches and I shook them into a box then dumped the bees in the nucs. No excluders. They stayed. However the first swarm, from a branch, after being dumped into the nuc showed signs of wanting to vamoose so I placed a blocking screen at the entrance and made up some sugare water quickly and did a liberal spraying of that in the entrance and that cooled them off, like, RIGHT NOW, and they stayed after I removed the screen. The second swarm from a branch stayed in the nuc box with no trouble but I did do a liberal spraying of sweetwater.
One other swarm was attached to a three foot tree stump and those I placed a nuc box under and with a scraper caused the majority of the bees to fall into the box. The stragglers made their way in eventually.
Another swarm was on the ground on the lawn spread about 2 X 3 feet. I poked around and found the queen, placed her in the nuc box and eventually the remainder of the bees marched in like in the crusades. That was interesting and I have pics of that little episode. Anyone wanting to see, send your e-mail address I got plenty of pretty good pics.
So in summation, four swarms, no excluder, plenty of honey laced sweetwater sprayed on everything, worked for me. Of course while doing this I sang some sweet tunes to go along with the program, like " Ruby don't take your love to town "
